Frequently asked questions
Where does this data come from?
From road-flood sensors of the Bangkok Metropolitan Administration's Drainage and Sewerage Department, published in real time at weather.bangkok.go.th/flood
How deep is too deep for a sedan?
Around 30 cm or more risks water getting into the engine, and fast-flowing water only 30 cm deep can sweep a sedan away. Avoid that route.
Who do I call if I'm stranded by floodwater?
Call the DDPM hotline 1784 or add LINE @1784DDPM. If anyone is injured, call 1669.
How can I tell if more heavy rain is coming?
Check the TMD rain radar and the forecast map on this site's home page.
